dwf- IMPROVEMENT IN LUBRICATING DEVICES FOR BOLT-THREADIN'G MACHINES.

The Schedule referred to in these Letters Patent and making part of the sameA To all whom Nanay concern;

Bc it known that I, WiLLian ARMSTRONG, of Kent, in the county of lortage and State of Ohio, have invented a Self-0iling Device for Bolt-cutting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure 1 is a front view of a cutter-carrying head, having the oiling device applied toit. i l

Figure 2 is a section, taken diametrically through the cutter-carrying head with the oiling device applied to it. l l

Figure 3 is a perspective view of the oiling device.

Similar letters of reference indicate corresponding parts in the three figures. i

rlhe object of this invention is to apply an adjusty able funnel to the face of the cutter-carrying head of a bolt-cutting machine in such manner that at every revolution of said head a given quantity of o il will be dipped from an oil-reservoir below, and elevated and poured upon the bolt at the point where it is being cut, as will be hereinafter explained. l

'lhe following description will enable others skilled in the art to understand my invention. A r

The circular head A, shown in iig. 1, is intended to represent the cutter-carrying head of a bolt-.cutting machine, to which head the cutters, which are not shown in the drawing, may be applied in the usual well-known manner, so that the bolts are cut at the center of the central opening w. y

On one side of this head a cup, B, is applied by means of a pivot or set-screw,`e, passedthrough an arm, B', into the head, and set up suliiciently tight to prevent the cup from slipping out of the. desired lp0- sition.

.lhis cup is of a tapering forno, its smallest end or dischargingnozzle being curved into the central opening a, so as to deliver the oil at the proper point on the bolt, which is being cnt in the center of this opening a.

'lhe largest end ol' the cup has a dipping-lip, c, and

also an opening for allowing the oil dipped up to How into'the cup.

The cup is adj usted for operation, so that its lip c will dip, more or less deep, into a reservoir, lG, of oil,

which is arranged in any convenient manner beneath the head A.

. Bygadjusting the cup about its pivot c, any desired quantity of oil'can be dipped from the reservoir at .each revolution ol the cutter-carrying head.

It will bc seen from the above description that as Athe cup B sweeps Llirough the oillieservoir, it will take up a given quantity of the oil contained therein,

and as the cup is carried toward the highest point ot' its revolution, the oil will run toward the center of the head A, and be delivered from the nozzle Z1 uponA Witnesses:
